SEATTLE – Jensen Maritime Consultants, a Crowley Maritime Corp. company, announced this week it is designing a new 5,150-hp, twin ASD tug for McAllister Towing & Transportation. The Eric M. McAllister will be built at Senesco Marine LLC, North Kingstown, R.I. It will be the 10th JMC-designed and first Tier 3 tug in McAllister’s fleet.
The tugboat is expected to be delivered in mid-2013.
The tug will be the third in a series of similar Jensen-designed McAllister tugs, following the Andrew McAllister and Rosemary McAllister, both built in 2008. The new tug will operate in the New Bedford, Mass., area, where it will primarily perform ship escort work in Buzzards Bay, Mass.. The Andrew McAllister is now operating out of Portland, Maine, and the Rosemary McAllister is currently under charter.
“We are pleased that the longstanding partnership we have with McAllister has given us the opportunity to design another environmentally responsible tugboat for use on the East Coast,” JMC VP Johan Sperling said in a statement. “The state-of-the-art design developed is yet another example of Jensen’s full scope of industry-leading naval architecture and marine engineering capabilities.”
The design will not only give McAllister improved performance over the previous two designs, the press release said, but also an environmentally friendly tug with lower emissions and reduced fuel consumption to meet the Environmental Protection Agency’s Tier 3 marine emissions regulations. Tier 3 standards require a 50 percent reduction in particulate matter and a 20 percent reduction in nitrogen oxide.
At 96’x34′, the Eric M. McAllister will be powered by two Caterpillar 3516CHD Tier 3 engines and two Schottel 1215 Z drives. The package will provide an estimated running speed of 12 knots and a bollard pull of 67 tons.
Additionally, the tug’s firefighting system will produce 11,967 gpm through a pair of FFS 1200LB remotely controlled monitors. The water is delivered through a single FFS SFD 300-400 pump powered by a Cat C32 engine. The monitors will have a 1,500-gal. tank, foam capability and a deluge system.
Towing machinery includes a JonRie 250 Escort winch with full render/recover on the bow and a JonRie 512 tow winch with a spool capacity of 2,100′ of 2 ¼” wire on the stern.
